Twitter / X Image Sizes 2026: The Complete Guide

Using the wrong image size on Twitter / X means your posts get cropped in the timeline, your cover photo looks off on mobile, and your profile photo appears blurry. This guide gives you every Twitter X image size for 2026 — posts, cover photos, and profile pictures.

Post Images: Design for the 2:1 Timeline Crop

When you upload a post image on Twitter / X, the platform stores it at 1600×900 px (16:9), but the timeline preview shows it cropped to approximately 2:1. That means the top and bottom of your image get cut off in the feed.

To make sure your key content is always visible:

Design your main subject and text in the central horizontal band of the image

Avoid placing anything critical in the top or bottom 20% of the frame

Upload at 1600×900 px — this is the optimal resolution for both the timeline crop and the expanded view

If you click through to expand the image, the full 16:9 version is shown.

Cover Photos: Keep It Simple

Your Twitter / X cover photo displays at 1500×500 px — a very wide, short banner. On mobile, the left and right edges can be cut off, so the central portion is the only safe zone.

Design tips for cover photos:

Keep all important content in the central 60% of the width

Use simple backgrounds or gradients that look good when cropped

Your profile photo circle overlaps the bottom-left area — avoid placing important content there

Keep text minimal and large so it reads even when compressed

Profile Photos: Minimum 400×400 px

Twitter / X displays profile photos at around 200×200 px, cropped into a circle. Upload at 400×400 px minimum — larger is better on high-DPI screens.

Center your subject and leave space on all sides, because the circle crop removes the corners of your square image.

File Size Limits on Twitter / X

Images: up to 5 MB per image

GIFs: up to 15 MB on web, 5 MB on mobile

Maximum 4 images per post

For the best quality, keep single images under 1 MB and upload as JPG for photos or PNG for graphics.

Key Takeaways

For post images, upload at 1600×900 px and design your key content in the central horizontal band to survive the 2:1 timeline crop. For cover photos, use 1500×500 px and keep everything important in the center. Profile photos should be at least 400×400 px so they look sharp on all devices.
